To all whom it may concem: Y 7

Be it known that I, HERMANN DEPPER- MANN, a subject of the Emperor of Germany, residing in lVilhelmstrasse 8, Nowav-sesNeuendorf, near Potsdam, Germany, have invented certain new and useful 1mprovements of YVinding Machines for Thread-Buttons, of which the following is a specification.

This invention relates to improvements in and pertaining to the manufacture of thread buttons, these improvements being applicable also to the manufacture of other similar objects, such for example, as thread-covered rings for embroidered ornaments.

Various attempts have already been made to produce thread buttons by mechanical means, but none of these have proved satisfactory as the apparatus proposed has been both too complicated and too expensive.

According to the present invention there is employed a winding ring which is passed through the wire ring forming the framework of the button for the purpose of winding thread aroundit. Winding-rings of this kind have already been used for other purposes, but they have all been unsuitable for use in the manufacture of thread buttons as they have carried bobbins which were not adapted for the winding of rings of such small size as are employed in the manufacture of thread buttons. More particularly ii would have been impossible to pass a winding ring of the kind heretofore usual through the ring which constitutes the framework of the button.

The wire ring having been first covered with thread by means of the'winding ring, next has thread wound across it by the passiug of the winding ring around it.

The winding ring employed possessesthe nove feature that it carries a cop that enables a bobbin core to be dispensed with, in a groove, so that it takes up but little room,

' and nowhere projects beyond the external periphery of the ring. It is essential that this cop should accommodate itself to the circular shape of the ring. It is moreover characteristic of a winding ring in accordance with this invention that it is provided with an open slot to enable the button ring to be placed in position, that is to say, to be movedfrom the first to the second winding position.

Figures 1 to 11 of the accompanying drawings illustrate in various views a machine in, accordance with this invention, while Figs. 12 to 14 illustrate the button.

Referring now to the drawings: The button ring 1 and the winding ring 2 are both shown in Fig. 1. The button is supported by four spindles 3, 3 and 4, 4 as shown also in Figs. 8 to 11. Around each of the spindles there runs a groove 5 into which there is inserted a rubber ring 6 which serves for increasing the friction whereby the button ring is carried along. The spindles besides serve to guide the winding ring laterally. The spindles 3, 3 can be turned aside to enable the button ring to be placed in position. Their lower ends rest in footstep bearings 7 while somewhat higher up-they are guided in slots 8 in an arm 9. The footstep bearings 7 have sufficient play to enable the spin dles to be swung out. In the arrangement shown in the drawings the spindles 4 are also mounted in bearings at their upper ends. This arrangement, however, more particularly when the buttons to be produced are small, involves difficulty in placing the ring 1 in position; and it is therefore preferable to guide the spindles 4 by'means of a neckbearing arranged below the ring 1 and to leave them entirely free at the top, in which case their form-is the same as that of the spindles 3 and the ring 1 will lie completely free on its upper side.

. The spindles are actuated by means of a worm 10 which meshes with worm-wheels 11 on the spindles 4 (Figs. 1 and 2). The mov able spindles 3"a-re connected with the fixed spindles 4 by means of an elastic band 12 which actuates the-former without preventing them from being turned aside. The worm 10 is mounted on a shaft 13 which is rotated from the main driving shaft 14 by means of change speed gear. The main shaft 14 carries a driving pulley 15 over which there passes a driving band 16, which is driven either by a small motor or by a pedal driving mechanism similar to that of a. sewing machine. The shaft 14 in some cases may be driven from a'hand-actuated shaft 1 1. The clutch 21 is adapted to slide on the shaft 13 but is so connected with the shaft through the key 22 that the shaft rotates with it. According as the clutch 21 is connected by means of the lever 23 and a cone of the clutch with the wheel 18 or the wheel 20 the shaft 13 will rotate at a higher or at a lower speed. The transmission ratios of the speed gear are such that when the shaft 13 rotates slowly, the button ring 1 makes 1 complete revolution, while the winding ring, in the case of large rings, makes about 150 revolutions. lVhen the shaft 13 rotates rapidly the speed ratio of these rings is about 1 to 50. it is, of course, possible to vary the speed ratio in accordance with the size of thread in use. The winding ring 2 is supported by 3 rollers 2e, 24: and of which the rollers 21 are rigidly mounted on an arm 27 fulcrumed on a pin 26 and are covered with leather to enable the winding ring to be more easily carried along. The roller 25 is mounted on a block 28 that slides in guides ina frame 29 attached to the lever 27 and is acted on by a spring 30 so that the roller 25 presses the winding ring 2 firmly against the rollers 2%. The upper end of the lever 2'7 is guided in a frame 31, which is provided with three notches 32 for retaining the winding ring 2 in its difierent positions. The lever 27 is provided for the same purpose with springpressed movable bolt The reasons for the various positions in which the ring can be retained by means of the notches will be hereinafter explained.

The rollers 2% are rotated by means of suitable spur gearing. On the main driving shaft 1% there is mounted a toothed wheel 31 (Fig. which drives another toothed wheel 35 connected with the lower roller 2% by means of the shaft 36. A similar wheel 37 is connected with the upper roller 21 by means of the shaft 38, and is driven from the wheel through an intermediate wheel 39, the provision of which is necessary since both of the rollers 2d must rotate in the same direction.

Figs. 1 and 3 show the lever 27 and the winding ring 2 in the position of rest while Figs. 8 and 10 show it in two d fferent working positions. As will be seen, in Fig. 8 the ring 2 runs through the button ring 1, while in Figs. 1 and 3 it is shown out side of the ring 1 in its position of rest. The curves 71:, shown in Fig. 8 by dotted lines, indicate the path of the slot during its swing and also indicate the correct dimensions of the slot. The thread %0 is shown in full lines'in the position corresponding to that of the winding ring 2, tions by dotted lines. It will be seen that the distance between the point at which the thread passes out of the ring 2 and the button ring decreases and increases as the winding ring and in other posi,

rotates. This necessitates the provision of a'thread tension-regulating device, which is illustrated in Figs. to 6.

These figures show clearly the groove running around the periphery of the winding ring 2 wherein the cop ll is located. From this cop the thread passes first through a. guide eye i2, thence between a pair of disks 4L4: which are pressed together by means of a spring 13 to another guide-eye L5, and thence through an eye it; to the per foration e7 below the eye 15, leaving the ring through this perforation. The eye 16 is not directly attached to the winding ring 2 but connected with it by means of an elastic cord or spring 48, the other end of which is attached to an eye 459 on the ring 2. lVhen the end of the thread leaving the rin is subjected to a pull, the elastic cord will be the first to yield and will continue to do so until the consequent tightening of the thread has overcome the clamping action of the disks ll. Should this happen beforethe eye 16 has come to lie in front of the perforation 17 the thread will at once begin to unwind from the cop ell. In the position shown in Fig. 6 it has however been assumed that this occurs only when the eye I 4-6 is located above the perforation -17 which however is really not essential to the satisfactory operation of the machine. Allthat is really necessary is that at the greatest distance between the eye 15 and the eye. 46 the thread is still sufliciently under tension through the return of the elastic cord 18. If it is assumed that the position of the eye 16, shown in Fig. 6, occurs when the distance between the place at which the thread leaves the ring 2 and the button ring is at its maXi- 'mum, the eye 46 will again assume the position shown in Fig. l when that distance decreases. The tension of the elastic cord will however remain and consequently also the tension of the thread.

Fig. 7 illustrates, a section through the winding ring. Attention is directed to the groove 50 with which the roller 25 engages. Fig. 10 illustrates the second working position of the winding ring, in which it passes around the button ring. In this case also the thread 10 is shown in different positions which will make it clear that in the position shown in this figure also, there occurs a variation in the distance between the point at which the thread leaves the ring 2 and the button ring, that is to say, that in this case also thethread tension-regulating device ust described becomes operative.

Figs. 9 and 11 illustrate in plan the manner in which the button ring is supported by the spindles 3 and 4, and also show the ring partially covered in accordance with the method of winding taking place at the time. From the drawing it will be obvious that the button ring will be wound with thread in the manner shown in Fig. 12 when the winding ring is in the position illustrated in Fig. 8 and in the manner shown in Fig. 18 when the winding ring is in the position illustrated in Fig. 10. Fig. 13 also shows the form in which the thread button leaves this machine and is conveyed to the tambour machine.

The preceding description renders it clear that all the work hitherto done by hand before the button is ready for the tambour machine can actually be done by means of a machine in accordance with this invention. The power required to operate this machine is small and, as already stated, it can consequently be operated by hand. If desired several single machines such as described may be arranged on a common driving shaft. In this case the speed gear and the pinions for rotating the rollers 2 L need not be duplicated, as for the purpose of driving the button ring it is only necessary to duplicate the spindles 3 and at in accordance with the number of the single machines while all the rollers 24: required for the single machine may be mounted on common shafts 36 and 38. If desired the spur gear described may be replaced by cord, band, or friction gear.

As has been herein-before stated, the invention may also be employed for covering thread covered rings for embroidery ornaments.
